This 3D model is a Tesla valve, a one-way flow device designed without moving parts. It uses a series of curved channels to let fluid flow easily in one direction (shown by the arrow) while creating resistance in the opposite direction by causing turbulence.

How It Works:

• In the forward direction, the smooth design minimizes resistance for efficient flow.
• In reverse, the loops force fluid into chaotic paths, increasing resistance and reducing flow.

Applications:
Perfect for systems like microfluidics or low-maintenance devices where controlling flow without moving parts is essential.

This design is easy to understand and great for experiments or teaching fluid dynamics!
